Y-UN'ION FOR TRUSSED-AXLES.

' vSPECIFICATIoN forming part of Letters Patent No. 731,o93,detee1 June 16, 1903.

Application filed March 7, 1902. Serial No. 97,128. (No model.)

To @ZZ whom if may concern:

Be it known that I, WALTER C. BAKER, a

citizen of the United States, residing at Olevel land, in the county of Cuyahoga and State of Ohio, Yhave invented certain new and useful Improvements in Ys for Tubular Trussed Axles; and I hereby declare the' following to be a full, clear, and exact description of the' invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to Y-unions more especially adapted for use in connection with trussed axles, the function of the union.be

' brazing, or soldering in any manner the two in which the same can be formed, it is a clearY illustration of the invention.

In the drawings, Figure I is a view in end elevation of a Y-union looking at it from the outer end. Fig. II is aviewin side elevation of the same looking at it from its inner side. Figs. III and IV are respectively isometric and sectional views illustrating a blank which may be employed in constructing the union and also illustrating the method which I prefer to employ to carry out my invention.

A represents the axle member or the lower arm or socket of the union, which is preferably when finished approximately uniform in diameter throughout its interior surfaces. At the outer end of the arm or member A is a cup-shaped flange A', which is preferably formed so as to receive a separate cup-band A2 and also preferably provided with lugs a a' to engage a brace-rod. (Not shown.)

B represent-s an arm or socket, which extends at an angle of, say, approximately fortyfive degrees out Ifrom the arm or member A in the finished device. The arm or socket B is also preferably formed approximately uniform in interior and external diameter and is designed to receive and hold in position a curved trussed bar, thus holding the ends of the straight and curved tubes which form the trussed axle together. I call this member B the arch member.

Inasmuch as it is very essential that the Y- sen-tial that the arm or socket B be formed from the blank C. This I accomplish, pref-` erably, by successive operations of drawing out or stamping out, as suggested in Fig. IV of the drawings, which is accomplished in any wellknown manner and by the use of suitable dies. This drawing out or stamping is preferably done by forcing the material constituting the member B at an angle of about ninety degrees to the blank C, then by another operation forcing this material at an angle of about sixty degrees, and by a further operation forcing it to an angle of approximately forty-five degrees, which is its position with respect to the member A in the finished article. This leavesthe blank C in condition to be formed into the shape shown in Figs. I andII by drawing thev blank into a cylindrical or tubular shape around a mandrel or otherwise and brazing or securing the freeends C C2 together. In order that this may be accomplished more securely,I prefer that the ends C C2 be provided with interlocking dovetails c c. After the parts are formed as suggested in Figs. I and II and where it is desired to use a brace rod or bar to brace the end of the axle to the reach an open space D is left in the cupshaped ange A', and hence it becomes advisable to use a separate cup-shaped or ringshaped piece A2 to act as a continuous dustband. This separate piece A2 tits snugly within the flange A' and is held in place tightly by bringing the lugs ci ct' together When the brace-rod is fastened between them.

It is to be understood that I do not Wish to limit myself to exact details or steps employed in carrying out my invention, inasmuch as they may be varied Without departing from my invention. For instance, both the arms A B may be drawn from plate metal by means of suitable dies Without the necessity ot' forming the article from an open blank, as hereinabove set forth.

It will be seen from the above description that by forming a Y-union in. the manner above set forth lightness is attained and at the same time strength on account of the material used-viz., sheet-steel preferablyand that cheapness is attained, because when the articleis nishedsubsequent boring forfitting becomes unnecessary and the manipulation ofthe Y-union is reduced to a minimum.

What I claim is- 1. A Y-union made from a single blank of metal and consisting of an axle member and an arch member extending at an angle of approximately forty-five degrees to the axle member, a' cup-ange made integral With the axle member, and outwardly-extending lugs carried by said flange, substantially as described. l

2. As a new article of manufacture, a Y-union made from a single blank of metal and consisting of an axle member, a cup-ange integral with one end of the axle member, and an arch member integral with the axle member and extending therefrom at an angle of approximately forty-five degrees, substantially as described.

3. A Y-union consisting of a tubular axle member, a cup-flange integral with one end of the axle member, lugs integral with the cup-flange, a cup-band within the cup-Hange, and an arch member integral with the axle member and projecting therefrom at an angle of approximately forty-five degrees, substantially as described.

Signed by me at Cleveland, county of Cuyaboga and State 0E Ohio, this 2d day of February, 1902.

VALTER C. BAKER.
